BENCHMARK SOFTWARE
The software in use for today’s analysis is typical of many of our reviews and consists of Crystal Disk Info, ATTO Disk Benchmark, Crystal Disk Mark, Anvil’s Storage Utilities, AJA, TxBench, as well as Sustained Disk Transfer, Temperature and True Data Transfer Rate Testing. Our selection of software allows each to build on the last and to provide validation to results already obtained.
ATTO Disk Benchmark is perhaps one of the oldest benchmarks going and is definitely the main staple for manufacturer performance specifications. ATTO uses RAW or compressible data and, for our benchmarks, we use a set length of 256mb and test both the read and write performance of various transfer sizes ranging from 0.5 to 8192kb. Manufacturers prefer this method of testing as it deals with raw (compressible) data rather than random (includes incompressible data) which, although more realistic, results in lower performance results.
CRYSTAL DISK BENCHMARK VER. 8. 0.4 X64
Crystal Disk Benchmark is used to measure read and write performance through sampling of random data which is, for the most part, incompressible. Performance is virtually identical, regardless of data sample so we have included only that using random data samples.
THROUGHPUT
IOPS
ANVIL STORAGE UTILITIES PROFESSIONAL
Anvil’s Storage Utilities (ASU) are the most complete test bed available for the solid state drive today. The benchmark displays test results for, not only throughput but also, IOPS and Disk Access Times. Not only does it have a preset SSD benchmark, but also, it has included such things as endurance testing and threaded I/O read, write and mixed tests, all of which are very simple to understand and use in our benchmark testing.
The AJA Video Systems Disk Test is relatively new to our testing and tests the transfer speed of video files with different resolutions and Codec.
TxBench is one of our newly discovered benchmarks that we works much the same as Crystal Diskmark, but with several other features. Advanced load bench-marking can be configured, as well as full drive information and data erasing via secure erase, enhanced secure erase, TRIM and overwriting.

The ProGrade Gold card tested well, but it’s a 1 TB card. The 128 GB ProGrade Gold card is exceptionally slow as tested in my Z6, Z7ii, and D850. While these tests are valid, it’s the in-camera performance that matters and it can be quite different.
